To all whom it may concern:

Be it known thati I, ALL N T. Lonngia citizen of the United States,residing at Memphis, in the countyofHalland State of Texas, haveinvented certain new and useful" Improvements in CottomBo ll-CleaningMachines, of'which the following'is a specification, reference being hadto the accompanying drawings. I I ,V II This invention relatestoan'imp'r'oved cotton boll cleaningor ginning machine, and

I one of the'objects of the invention is the provision of an apparatusof thiskind for efliciently breaking I the. cottonv bolls and thoroughlyseparating tl1e,'-motes'and dirt from the cotton. II I II I I -c c I I Afurther object of theginventi'on is to provide an apparatus which isverycompact,

simple and I practical in construction,. and yet constructed-whereby"thecotton during its passage through the machinewill receive a plurality ofcleaning processes, so. that all the motes anddirt may beremoved fromthe provision of a machine of this klndincluding duplicate mechan smsonesuper 7 imposed cotton.- v 1, r A further object: of theinvention isthe with relation to the other and being socoupled that. the cottonbolls'after passing through the superimposed mechanism may betransferred to the other' mechanism,

1 thereby giving the cotton 1 bolls a: double cleaning, separating themotes and dirt from the cotton, during each cleaning processfdischargingthe dirt and motes from both'cleaning processes through a single"discharge I, chute and delivering .the cotton, when cleaned, .through asingle outlet chut I I scope of whatis claimed.

The invention com Y ises-"further features I vided they are comprehendedwithin the q and combinationof'parts, aswillbe chereinafter set forth,shown inthe drawings andv claimed. i I I t In the drawings: l Figure 1is a vertical sectional View Specification ofLettr's la tent- P t tApplication filed machinefi I y I V v c I,

The invention having been set forth, what is claimed as new and usefulis:

1. In a cotton cleaning machine, the com- 'bination with a casing havinga'boll chamber, of a cotton cleaning mechanism in said chambercomprising a conveying screw and cotton gathering saws operative inparallel I planes on an axis parallel with the screw, a

knocker roll. offset above and between the y screwand the saws andprovided with longitudinally extending spaced flanges adapted to'knockthe bolls back upon the feed screw,

and a hinged combined deflector and guard plate adjustable toapproximate the longitudinal edges of the knocker flanges of the knockerroll to assist in knocking the bolls back toward and upon the conveyer.

1 2, In'a cotton cleaning machine, the combination with. a casingprovided with a cotton cleaning chamber having a screen concave in'itsbottom, of a picker roll operable concentric with the concave forforcing or feeding t-hetrash through the concave, .a conveyer screw forfeeding the cotton bolls into the chamber and upon the picker rolls,cotton gathering saws operable in parallel planes and upon an axisparallel with the feed screw, of a knocker roll ofi'set above binationwith a casing'provided with a cotton cleaning chamber having a screenconcave in its bottom, of a picker roll operable concentric with theconcave for forcing or feeding the trash through the concave, a conveyerscrew for feeding the cotton bolls into the chamber and upon the pickerrolls, cotton gathering saws operable in parallel planes and upon anaxis parallel with the feed screw, of a knocker roll ofli'set above andbetween the saws and the feed screw having knocker flanges extendinglongitudinally thereof, a combined guard and deflector having a rightangle'flange extending. in a horizontal plane toward and in a directionof the axis of the knocker rolland adapted to approximate thelongitudinal edges of the knocker flanges, and means for adjusting thecombined guard and deflector whereby its flange may be moved toward andfrom the knocker flanges. I r

4. In a cotton cleaning machine, the combination with a casing having acotton cleaning chamber, of a cotton bolling mechanism in said chamber,said casing having a hopper communicating with said chamber to feed ofthe. hopper adapted to approximate the longitudinal edges of saidknocker flanges for knocking the bolls back toward the boll ingmechanism, and means for adjusting said combined deflector and guard.

5. In a cotton cleaning machine, the combination with a casing providedwith a cleaning chamber, of a bolling mechanism in said chamber, saidcasing having a hopper communicating with said chamber, a knocker rollabove the bolling mechanism and between operating members thereof, bollknockers angular in cross section arranged longitudinally of the knockercylinder and extending radially, a combined guard and deflectorpivotally suspended from the top of the casing and having alongitudinalknocker flange at its lower end disposed in a horizontalplane toward and in parallelism with the axis of the knocker roll toassist in knocking the bolls back toward and upon the bolling mechanism,and an element threaded in the wall of the casing and being swivellyconnected to said combined guard and shield for adjusting thesame-whereby-the flange of the guard may approximate the longitudinaledges of the knockers on the knocker roll.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
